Hi all, i spent quite a bit of money getting my 1700x system together even having made the mistake of buying dual rank memory in the beginning and finding out that i couldnt go past 2400mhz and then having to purchase single rank Samsung b-die memory so it could run at the rated speed, im now having issues with getting 3466mhz to work correctly. My board is an Asus Prime Pro x370 with the latest 0805 bios.

Im currently sitting on 3333mhz c14 stable at 1.38v but In order to get 3466 running (not stable) i need 1.425v which is too much imo for everyday use, when can we expect the next update in microcode to fix this?

That's up to ASUS. The Prime X370-Pro is a horrid board, so bad you'd think it was made by MSI or Gigabyte given the bugs and low quality (I had it for 2 months, I had to replace it with a Crosshair VI). Memory compatibility is very much motherboard specific, as my RAM (Corsair DDR4-3200) couldn't run reliably past 2800 on the X370-Pro, and that was with the higher timings of DDR4-3200, but on the Crosshair VI they work at full 3200mhz.

You obviously have no idea what youre saying are you drunk? X370 pro isnt a "horrid" board. Ive had no bugs besides being held back by memory. Once single rank modules went in i was able to jump from 2400-3333 reliably. So youre saying you couldnt wait for an update to see if it would fix any issues you may have had so instead you go out and pay top dollar for a ch6 which cant even get 3600mhz stable effectively supporting the fact that the most expensive board is the "best" lol (face palm) Yes its got more features than the x370 pro but its double the price. If i were you then id want my board to be stable at 4000mhz from the moment i purchase and install it. Secondly why on earth are you using Corsair ram lolll

Latency is still an issue and no where near as good as my old haswell ddr3 system 39ns as apposed to 68-69ns im getting now.

Because I was tired of waiting for ASUS to fix the memory problem with that board, sick of waiting for the temperature glitch to be fixed, and sick of waiting for the header dropout issue to be fixed, so I bought a better board. So if you have any complaints, they should be directed at ASUS, AGESA 1.0.0.6a solves a lot of memory issues, but it is motherboard dependent and not all boards respond to it in the same way. Future AGESA releases have not been announced.

after looking at taiphoon timings for ram sticks. it seems like 1 of the reasons these b-dies can clock higher is they seem to allow for alot higher ( TRC) timings than factory specs. i first noticed this on the flare-x but these rgb's same thing. . example rgb trc time should be 52 @3600mhz but actual is 85 and 84 for flare-x 3600 . it seems to me the corsairs and or hynix just wont let those timeings jump up. im thinking trc for 4000 should be around 98 but will it need to go over 100 if so can it in the bios.? hmmm ...just a thought. eeeh

black_zion i watched you struggle with that 58 trc and mentioned in other thread get that up # but didnt seem you could do so. this could be the big problem area.

bo55 the flare-x 3200mhz stick@3600 i didnt even try running under 1.42 i saw a performance drop so i know i was close i bumped up a bit and stable. 10% over volt safe on high end sticks. though i never recommend but ive ran gskills way higher than 10% for years no issues. 1.42 isnt bad these sticks are awsome.

the f4-4000c18 gzbr ... the rgb's in previous post was friends and rare case good silicon luck and they ran stock volts.

Thats awesome. Yeah i have the 2x8gb 3733 Trident Z kit and to even get 3466 running i need 1.425v and its not stable at all, imo thats way too many volts for that frequency, however 3333 c14 is solid at 1.38v. Yeah your friend is one of the very few who can get 4ghz on memory running. Im still hoping amd hasnt dropped the ball on ryzen just yet, i feel as though more optimisations/improvements on performance can be made.

i got the trident z rgb 4000 kit got 3600 but not stable. 3200 solid but not worth it. i may try 1.55 volts see if it flys or not. you can go .200 over on g.skills but ive seen just for testing .300 to see where it will go.. dont keep it that high lol. .150 safe zone. those trident z wont even let a l3 cache test on cpu pass. so there no good.. intel cant even get the same rgb's to run as intended.. seems odd.

on the other hand for 100$ less the flare-x 3200 kit will run 3600mhz solid as a rock 400mhz over stock. per g.skill timings 16 16 16 18 38 for 3466mhz and just plug in 3600mhz a small boost on volt and better latency than stock and speed ofcourse.. with no base overclock... friggin sweet... wish they made those in higher frequency dang...
